Improve Ansible.Basic.cs tempdir uniqueness (#80328)

* Improve Ansible.Basic.cs tempdir uniqueness

The current tempdir naming scheme can result in the same name if the
remote worker starts at the same time as another. By using the process
id it should add enough uniqueness to avoid this situation.

* Fix sanity issues

* Fix up compile issue on older hosts
